Instrument panel with an airbag flap

摘要

An interior part, such as an instrument panel, for vehicles, for example motor vehicles is disclosed. The interior part includes an injection-molded rigid carrier with a front side and rear side, at least one groove on the rear side of the carrier, along which the carrier can rupture in order to form an airbag flap. The groove base of the groove lies at a distance from the front side of the carrier. The groove is formed in the mold. The front and rear sides of the carrier have the shape of a closed outer skin. The carrier includes a foamed core at least in the region of the groove.

主权项

1. An injection-molded carrier part for a vehicle, wherein the carrier part is configured to fracture when an airbag of the vehicle unfolds, the carrier part comprising:
a front side and a rear side, wherein the rear side is configured to face the airbag; and a plurality of grooves having at least a first groove and a second groove on the rear side of the carrier part, along which the carrier part is configured to fracture to form an air bag flap, wherein:
the plurality of grooves extend inward from the rear side toward the front side of the carrier part, anda groove base of each of the plurality of grooves terminates at a distance from the front side of the carrier part; and a foamed core between the front side and the rear side, where the foamed core is located at least in a region of the plurality of grooves, wherein the foamed core further includes regions of different densities, wherein:
a first region includes an outer boundary having:
a first region width defined by a cross-sectional width of the first groove, wherein the cross-sectional width of the first groove extends in a direction along the rear side of the carrier part, wherein the first region width is constant in a direction extending linearly towards the front side of the carrier;a second region includes an outer boundary having:
a second region width defined by a cross-sectional width of the second groove, wherein the cross-sectional width of the second groove extends in a direction along the rear side of the carrier part, wherein the second region width is constant in a direction extending linearly towards the front side of the carrier;a density of the first region is lower than a density of a region surrounding and adjacent to the first region;a density of the second region is higher than a density of a region surrounding and adjacent to the second region; andthe density of the first region is lower than the density of the second region.
